LLM Evaluation Framework

Production-grade open-source LLM benchmarking. Evaluate GPT-4, Claude, Gemini, Mistral and Llama on 5 metrics — side by side — in one command.

What This Is

This is the model card / hub page for the LLM Evaluation Framework. The framework itself is a Python tool, not a neural network weight — this page serves as the HuggingFace hub entry point linking all resources together.

Quick Start

bash

pip install llm-evaluation-framework
export OPENAI_API_KEY="sk-..."
llm-eval run --model gpt-4o-mini --benchmark mmlu --samples 100

5 Evaluation Metrics

Metric	Description	Output
Accuracy	4-strategy cascade: exact → normalized → MC → fuzzy	0.0–1.0
Latency	p50, p75, p90, p95, p99 percentiles + SLA violation rate	ms
Cost	Real token counts × pricing table for 15+ models	$/1K tokens
Hallucination Rate	Linguistic signal analysis (v1), NLI planned (v2)	0.0–1.0
Reasoning Quality	Chain-of-thought depth scoring	1–10

Supported Models

Provider	Models
OpenAI	GPT-4o, GPT-4o-mini, o1, o1-mini, GPT-3.5-turbo
Anthropic	Claude 3.5 Sonnet, Claude 3.5 Haiku, Claude 3 Opus
Google	Gemini 1.5 Pro, Gemini 1.5 Flash, Gemini 2.0 Flash
Mistral	Mistral Large, Mistral Small

Sample Benchmark Results (MMLU, 100 samples)

Model	Accuracy	Latency	Cost/1K	Hallucination	Reasoning
GPT-4o	88.2%	892ms	$0.0080	1.8%	8.4/10
Claude 3.5 Sonnet	87.6%	1240ms	$0.0090	2.1%	8.6/10
GPT-4o-mini	78.4%	432ms	$0.0003	3.2%	7.2/10
Gemini 1.5 Flash	76.8%	380ms	$0.0001	4.1%	6.8/10
Claude 3 Haiku	74.2%	410ms	$0.0010	4.8%	6.5/10

Key finding: GPT-4o-mini achieves 88% of GPT-4o's accuracy at 4% of the cost.
